An either-handed replaceable mouse includes: a mouse body, having a first button part and a second button part, and a replaceable top cover, covering the mouse body and having a first button area and a second button area. The first button area and the second button area are correspondingly located on the first button part and the second button part respectively. During replacement of the replaceable top cover, a height from the top of the first button area on the first button part to the bottom of the mouse body is greater than or less than a height from the top of the second button area on the second button part to the bottom of the mouse body.

A computer mouse with a swingable palm rest cover includes a main body, a switch module, buttons, a magnetic sensor and a magnetic element. The main body has an upper housing and a lower housing. The switch module is disposed in the main body and connected to a circuit board. The buttons are movably disposed on the main body. The palm rest cover is slidably disposed on the upper housing of the main body. The magnetic sensor, which is connected to the circuit board, is disposed on the upper housing or the lower housing. The magnetic element is disposed on the lower housing or the upper housing. When the palm rest cover is swung to left or to right, its displacement can be sensed by the magnetic sensor and the magnetic element, so as to produce a pressure sensing signal and output an analog signal.

In certain embodiments, an input device includes a chassis and a depressible actuator disposed on the chassis that, when depressed, generates and sends a control signal to a processor, where the actuator is coupleable to a removable button cover that provides user-access to activate the actuator, and a removable blank cover to prevent user access to activate the actuator. The button cover and blank cover can be separate from the chassis and may directly attach to the actuator. The input device can further include a second depressible actuator disposed on the chassis that, when depressed, generates and sends a second control signal to the processor, where the second actuator is coupleable to the button cover and the blank cover.

Aspects of the invention include a computer peripheral device comprising an input element that operates based on a performance characteristic, an electropermanent magnet (EPM) assembly including a permanent magnet configured to generate a magnetic field and a magnetizing assembly configured to set an intensity of the magnetic field generated by the permanent magnet, and a magnetorheological (MR) material coupled to the input element. The MR material has a viscosity that changes based on the magnetic field and affects the performance characteristic of the input element.

A mouse having a digital key and an analog key includes a mouse body having at least one first key and at least one second key, at least one digital switch disposed at a position corresponding to the first key, and at least one analog switch disposed at a position corresponding to the second key. The analog switch has a magnetic element and a magnetic sensor, the magnetic element is connected to the second key, and the magnetic sensor is disposed at a position corresponding to the magnetic element. When the second key is pressed by a user, a relative distance of the magnetic element and the magnetic sensor change, so that a strength of an analog signal output from the analog switch is changed relative to the distance of the magnetic element and magnetic sensor.

A computer controlled pointing device having, a telescoping wrist support integral with and associated with the pointing device, so as to permit adjustable extension and retraction from the pointer device housing, to accommodate the preferred support position of an individual user's wrist. The means from effecting such adjustable incremental extension and retraction of the wrist support includes coupling means for releasable locking of the wrist support in a fixed position relative to the housing of the pointing device.

A computer mouse with an adjustable palm rest includes a main housing defined with a longitudinal direction and a traverse direction and has a carriage. A connecting base is rotatably connected to the carriage along a first axis. A supporting casing has a front wall and a rear wall. A palm-resting cover is fixed to the supporting casing. The front wall is closed to the connecting base. The supporting casing is rotatably connected to the connecting base along a second axis. The supporting casing can be arranged at different oblique angles related to the connecting base. A positioner chain is formed on a surface of the connecting base or the supporting casing and has a plurality of positioning dimples. A positioning assembly abuts against one of the dimples and retains the supporting casing at one of the oblique angles related to the connecting base.

An ambidextrous mouse is disclosed. The ambidextrous mouse is configured for both left and right handed use. The mouse may include right handed buttons on the front side of the mouse and left handed buttons on the back side of the mouse. The user may change the handedness of the mouse by rotating the mouse about a vertical axis of the mouse such that the left hand can use the left hand buttons and the right hand can use the right hand buttons. The mouse may include a handedness selection system for configuring the mouse for right handed or left handed use even though the mouse has the capability for both right and left hands.

Apparatus including: hand-controllable signal-generating device that includes body having top side, and bottom side spaced apart from and facing away from top side, bottom side being configured for facilitating displacements of body over working surface in two-dimensional directions, body having biaxial-displacement detector configured for generating biaxial displacement signals representative of displacements of body in two-dimensional directions; and signal transmitter configured for communicating biaxial displacement signals to external electronic processor. Body has palm rest on top side; palm rest includes palm contact surface having contour for receiving portion of palm of person's hand into contact at position on palm contact surface. Contour of palm contact surface is configured for facilitating control by portion of palm of person's hand, being in contact at position on palm contact surface, of displacements of body in two-dimensional directions over working surface. System including digit-controllable signal generating device and hand-controllable signal generating device. Related processes.
